Users of mobile terminals in a communication network are provided controlled access to files in a file system through the steps of configuring the files as a file body containing a file content and a file header containing content profile information; providing a security identity module and a secure agent; storing in the security identity module user profile information identifying a set of content profiles allowed for access to the file system; extracting, via the secure agent, the content profile information from the headers of the files; retrieving, via the secure agent, the user profile information stored in the security identity module; checking the user profile information and the content profile information; and providing the user with access to those files in the file system for which the user profile information and the content profile information are found to match.

A digital memory such as a memory card for mobile communication equipment, is adapted to be accessed by a plurality of users and have protected data stored therein. The memory is dynamically partitionable in private memory areas for storing data therein and has associated therewith a secrecy tool for securely allocating to the users respective private areas and permitting the users to access the respective private areas via a secure session channel to perform read/write commands in the respective private areas. Typically, the memory/card includes: a card interface controller for managing a physical communication layer between the digital memory and external host equipment, an internal memory having associated therewith a hardware lock to control access to the internal memory, a set of cryptographic modules to manage the secure session channel between the users and the digital memory, and a memory certificate for certifying a public key associated with the digital memory.

A CAM memory is supplied targeted at storing data words whose bits can take on an indifferent logical value besides two complementary logical values. it includes a matrix (MA) of memory cells in which a pair of cells is assigned to each bit that can take on a ternary configuration. circuits (CT1 . . . CT3, WR, SR; CT11 . . . SR1, CT21 . . . SR2) for memory (MA) matrix access control give access for performing comparisons during operation in the CAM mode or for writing/reading data by means of direct RAM mode addressing (FIG. 1).

An RM unit for remultiplexing multi-program audio-video streams transmitted within an switched digital video broadcasting service includes: as, FL1 . . . FLn, MS1 . . . MSn syntactical analysis and reception means receiving plural streams, separating data packets in each stream that can be transported directly to CF, AA, MA, TU means for generating output streams, from service packets that must be transmitted to an MP control unit for processing, in particular for updating service information to reflect the composition of output streams; ME means for temporary storage of data packets, separately for each input stream; and CF; AA, MC, TU output stream generation means that generate and send service users single program output streams or multi-program streams at a lower band than input streams obtained starting from the packets stored in such ME temporary storage means and from the service packets processed and entered into virtual ATM channels.

The switching element allows building up of ATM exchanges capable of processing cell flows at bit rates higher than 700 Mbit/s. It uses an architecture with output queues, implemented through a unique shared memory, suitably controlled in order to obtain spatial cell switching towards the outputs. ATM cells are converted into a highly parallel format by a structure named rotation memory, where through the cells are then transferred into the master memory. The rotation memory is used also for the inverse operations of format restoration towards the output. The element control circuit is entrusted with the generation of writing and reading addresses of the master memory, in order to carry out the switching proper.

Access to resources is controlled via a mobile terminal operatively connected to a network operator, wherein the mobile terminal has an associated authentication module configured for authenticating the mobile terminal with the network operator. The method includes the steps of providing in the mobile terminal at least one facility having authentication capability and adapted for accessing the resources, and authenticating the authentication module with the at least one facility, whereby the at least one facility is authenticated with the network operator via the authentication module.
